When this is complete, it is going to suddenly become much easier to develop robust communities on the Facebook platform. I have sent a message to Dave to find out if this is an open project or if it is just his and is friends. While I haven’t heard back yet, I will be sure to post a follow-up for any developers that want to participate in the project. Alternatively, you can simply post a comment below if you would like to contribute. It will be interesting so see how far along this goes in the coming weeks. Being a developer myself, I can speak from experience when I say this is surely a challenging task. Best of luck to Dave in completing the project! We will be excited to see the final app.
